Notorious lithium dendrite causes severe capacity fade and harsh safety issues of lithium metal batteries, which hinder the practical applications of lithium metal electrodes in higher energy rechargeable batteries. Here, a kind of 3D-cross-linked composite network is successfully employed as a flexible-rigid coupling protective layer on a lithium metal electrode. During the plating/stripping process, the composite protective layer would enable uniform distribution of lithium ions in the adjacent regions of the lithium electrode, resulting in a dendrite-free deposition at a current density of 2 mA cm-2 . The LiNi0.5 Mn1.5 O4 -based lithium metal battery presents an excellent cycling stability at a voltage range of 3.5-5.0 V with the induction of 3D-cross-linked composite protective layer. From an industrial field application of view, thin lithium metal electrodes (40 µm, with 4 times excess lithium) can be used in LiNi0.5 Mn1.5 O4 (with industrially significant loading of 18 mg cm-2 and 2.6 mAh cm-2 )-based lithium metal batteries, which reveals a promising opportunity for practical applicability in high energy lithium metal batteries.
